    RadControls version

    2009 Q1 +
    .NET version

    Visual Studio version

    2005 and later
    programming language

    browser support

    all browsers supported by RadControls


    Walter van Leur  (Walter) 
    The solution I’ve attached contains a project “TelerikRadGridLocalization” that does the localization of a RadGrid with the use of resource-files from codebehind. There are two resource-files. One for english and one for dutch language. There is another project (Demo) that demonstrates the use of the localization by showing a RadGrid on the Customers in the Nwind-db.

    How to use:

    §  Add project “TelerikRadGridLocalization” to your solution

    §  Add reference to project “TelerikRadGridLocalization”

    §  Add a RadGrid (for example ID="RadGrid1") to your page (for example default.aspx)

    §  In code-behind of that page (default.aspx.cs):

    ·         Add the following to to the Page_load():

    o    RadGrid1.Localize();
    This does the localization of most RadGrid-elements

    ·         Add the following to the OnPreRenderComplete():

    o    RadGrid1.HeaderContextMenu.Localize();  
    This does the localization of  the HeaderContextMenu

    protected void Page_Load(object sender, EventArgs e) 
    protected override void OnPreRenderComplete(EventArgs e) 
        //Translate the RadGrid's HeaderContextMenu 

    o    How it works:

    §  In project “TelerikRadGridLocalization” there is a class “RadGridLocalize” which contains extensions-mehods on the Radgrid.
    The method “
    Localize(this RadGrid radGrid)” calls the other localize-methods on the different elements of a Radgrid (such as the FilterMenu, SortingSettings etc…).

    §  Fot the localization of a RadGrid you can do a “RadGrid1.Localize()” in the Page_load of the page. To have the HeaderContextMenu localized you’ll have to do a “RadGrid1.HeaderContextMenu.Localize()” in the OnPreRenderComplete because the HeaderContextMenu isn’t yet available in the Page-Load.

    o    To see the dutch-localization working:

    §  Notice that in web.config the following is set to use the culture of the browser:

    ·         <globalization culture="Auto" uiCulture="Auto" />

    §   Run the solution

    §  Set the language to dutch in the browser:

    ·          Internet Explorer; Tools; Internet Options; Languages

    o     Add language “dutch (nl-NL)”

    o    refresh the page

    §  See the “Screenshot demo in dutch.docx”

    Why the doesn't RadGrid support localization using Recourse files by default? I hope to see this feature being added to RadGrid in the near future. For the time being: great work Walter. Just what I needed/wanted.

    Hello Hendrik,

    You can find sample RadGrid localization file in this code library thread:

    We will expose complete RadGrid for ASP.NET AJAX localization through resource files for the upcoming Q2 2010 release of the product, expected in the middle of July.

    Best regards,
    the Telerik team

    Is grid localization using recourse files by default already available? It seems that it's still not working without setting the culture property manually

    Hello Ron ,

    Indeed presently you need to set the Culture property of the grid explicitly to pick up the localization strings from resource files (if available).

    However, you may be happy to know that this will not be required for the next version of the control (Q2 2011), expected in the middle of the next month. It will accept the localization of the current thread by default while the Culture property can be used to specify it should differ from that set for the current thread.

    Best regards,
    the Telerik team
